swapping in d16a6

Hey im swapping a d16a6 in my crx dx,i already di the mpfi swap and etc.But i was just wondering what things i should do to the a6 before i put it in. The reason i ask is because its been sitting on the side for awhile (still has oil inside and the spark plugs) and it rained once and theres somewater in the spark plug holes. So what should i be looking for,or change? thanks
